the mixture is boiled. About 8 parts of commercial oleic acid are mixedWith about parts of mineral oil (petroleum) and the mixture is wellstirred, so that the two oils are now stirred together and vaporized, soas to leave the emulsion desired.

We claim:

Method of obtaining an emulsion for pre venting the formation of scaleson boilers, tubes, and similar articles, which consists in preparing afirst mixture of glycerin and Water, boiling said first mixture,preparing a second mixture of commercial oleic acid and petroleum,combining the two mixtures, and vaporizing the combined mixtures.
